I was so excited when I took my first cruise just like you were or will be. Did you overpack? I did and so will you. I had shoes for every outfit plus flip flops and tennis shoes plus deck shoes. I took several bathing suits and everything I packed filled 2 suitcases and a carry on. Needless to say, this was way before anyone charged for bags at the airport.
Now when I travel, I carry only what I absolutely need. I take two pair of black slacks, 2 pair of play pants, and one black skirt and any tops should go with them. I also take a black jacket as it will go over anything if I need to dress up. I take one pair of shoes other than what are on my feet. I wear very little jewelry other than my rings, one watch and one bracelet. You don't want to wear a lot of jewelry when you travel anyway. You are inviting disaster. Your makeup can be cut down as well. A little moisturizer, blush or bronzer, mascara, and a lipstick and you are set. Remember, you are on vacation, not going to meet the president. I now take one bag and no carryon. This will do me for 7 days.
Now if you just have to pack an outfit or two for every day, try to roll your clothes. You will fit more in your suitcase. Put hose and/or socks inside your shoes, and be sure when you pack a hat to fill it up with underclothes to save space. There is always more than one way to pack a suitcase.
What is your favorite ways to pack?
